can any buddy help me to in this issue iam not able to control spam mails from out side, on that spam mail some of the spam mails are struck in my server (queue viewer). any one mail struck on queue other mail ( normal mean regular mails) regular mails also strucked in my server queue viewer.

so in this issue with in my organization users sending mail also delivery very delayed and very late around some time one day or 8 hours and 10 hours also taking time to deliver.

hai my friend very thanks for giving suggestion but i found the problem whats. that is simply kaspersky exchange mailbox service problem that is. after stopped that service my mail server working fine and very fast and owa also without any errors we are accessing my owa.

Well, i never knew about the OWA issue of yours, but hey good troubleshooting done. However, i am a bit curious of Antigen could have messed up some thing - Exchange should have been able to report some dirty looking red errors in app logs.
